Addition of two forms in the third form

Question

Working on javascript to (+) from two forms and show it on the third one, but having a issue with that I want it to round the decimal to 2 as ,XX. And result is now showing in dot (.), how can I change it to show in comma ? It only let user write decimal values in dot, how can I change it to comma?

You are missing semi colon (;) end of var inputs. and value.toString().replace('.', ',') to output value replace dot (.) to comma (,).

Check this demo jsFiddle

jQuery

$(function() {
  var inputs = $('input[name="M_Fritt_Klor"],input[name="M_Total_Klor"]');
      output = $('input[name="M_Bundet_Klor"]');
    function parse(value) {
        return parseFloat(value.replace(',','.'));
    }
  inputs.keyup(function() {
      var value = parse(inputs[0].value)+parse(inputs[1].value);
      if (!isNaN(value)) {
          output.val(value.toString().replace('.', ','));
      }
  });
});

Yes, its work comma instead of dot.

Result

Thanks, is it possible to change it to only use comma in decimal values and show the result in comma ? Now it only supports dot (.): https://www.dropbox.com/s/2fc5c9wknbgtjtx/teste.png – user3185936 Mar 30 '14 at 13:31
Update answer check it – Jaykumar Patel Mar 30 '14 at 13:35
I want the result as it showing to be 23,6 not 23.6. – user3185936 Mar 30 '14 at 13:36
OP has a correct `var` statement in the linked fiddle code. Your code creates a global `output` variable... – Teemu Mar 30 '14 at 13:38
